查找具有重复值的数组并比较它们的键 [英] Find arrays with duplicate value and compare their key

问题描述

您好，我想找到具有相同值key EAN 的数组。如果存在多个记录，我想删除key ProductCount 值较低的记录。



例如我有一个数组。如你所见，有三个记录相同的ean （$ arr [0]，$ arr [1]，$ a [3]）。在找到具有相同ean的这些记录后，我需要比较其关键ProductCount的值，并将记录与ProductCount的最小值保持一致。你了解吗？



我会感谢任何建议。

Hello, I would like to find arrays with same value of key EAN. If multiple records exist, I want to remove the record with lower value of key ProductCount.

For example I have an array. As you can see there are three records with thesame ean ($arr[0], $arr[1], $a[3]). After finding these records with the same ean I need to compare their values of key ProductCount and keep the record with the smallest value of ProductCount. Do you understand?

I would be thankful for any advice.

$arr =array( 
"0" => Array
    (
        "ean" => 6900532615069,
        "productPrice" => 1140,
        "productCount" => 5
    ),
"1" => Array
    (
        "ean" => 6900532615069,
        "productPrice" => 1140,
        "productCount" => 50
    ),
"2" => Array
    (
        "ean" => 6900535364122,
        "productPrice" => 1140,
        "productCount" => 50
    ),

"3" => Array
    (
        "ean" => 6900532615069,
        "productPrice" => 1140,
        "productCount" => 10,
    ));

所以输出应该是

So output should be

$arr =array( 
"0" => Array
    (
        "ean" => 6900532615069,
        "productPrice" => 1140,
        "productCount" => 5
    ),
"1" => Array
    (
        "ean" => 6900535364122,
        "productPrice" => 1140,
        "productCount" => 50
    ));

我的尝试：



我试过这个以及对此的一些修改但没有成功。我试图这样做几天:(

What I have tried:

I tried this and some modifications of this but without success. I am trying to do it for days :(

function removeduplicateKeys($data){

$_data = array();

foreach ($data as $v) {
  if (isset($_data[$v['ean']])) {
    // found duplicate
    continue;
  }
  // remember unique item
  $_data[$v['ean']] = $v;
}

$data = array_values($_data);
return $data;

}

推荐答案

arr [0]，

arr [1]，

[3]）。在找到具有相同ean的这些记录后，我需要比较其关键ProductCount的值，并将记录与ProductCount的最小值保持一致。你了解吗？

a[3]). After finding these records with the same ean I need to compare their values of key ProductCount and keep the record with the smallest value of ProductCount. Do you understand?
